KEY ASPECTS OF INCIDENT RESPONSE & DIGITAL FORENSICS
PREPARATION
Assessment And Planning
- Initial consultation to understand the client’s environment and potential risks.
- Development of an Incident Response Plan (IRP) tailored to the client’s specific needs.
- Establishment of communication protocols and roles.
Training and Readiness
- Conduct training sessions for the client’s staff on incident response procedures.
- Set up and configure necessary tools and software for monitoring and response.
DETECTION AND IDENTIFICATION
Continuous Monitoring
- Implement advanced threat detection systems to continuously monitor the client’s network.
- Use SIEM (Security Information and Event Management) tools to aggregate and analyze security data in real time.
Incident Identification
- Proactive identification of anomalies and potential security incidents through automated alerts and manual reviews.
- Verification and categorization of incidents based on severity and impact
CONTAINMENT
Immediate Response
- Activate the Incident Response Team (IRT) upon confirmation of an incident.
- Implement quick containment measures to prevent further damage or spread.
Short-term Containment
- Isolate affected systems or networks to minimize the impact.
- Apply temporary fixes or patches as needed.
ERADICATION
Root Cause Analysis
- Perform a thorough investigation to identify the root cause of the incident.
- Remove malicious code, backdoors, or any other threats from the environment.
System Hardening
- Strengthen security controls and policies to prevent recurrence.
- Giving Advice for update software, apply security patches, and change compromised credentials.
RECOVERY
System Restoration
- Restore affected systems to normal operations using clean backups.
- Ensure that systems are fully operational and secure before bringing them back online.
Verification and Testing
- Perform rigorous testing to confirm that the threat has been completely eradicated.
- Monitor systems for any signs of residual threats or further attacks.
FORENSIC INVESTIGATION
Data Collection
- Gather and preserve evidence from affected systems in a forensically sound manner.
- Ensure all collected data is stored securely for analysis and potential legal proceedings.
Analysis
- Analyze collected data to understand the attack vector, techniques used, and the extent of the breach.
- Use forensic tools to reconstruct the timeline of the attack and identify compromised data.
REPORTING AND COMMUNICATION
Incident Report
- Provide a detailed incident report summarizing the findings, actions taken, and recommendations.
- Include an executive summary for non-technical stakeholders.
Communication
- Keep stakeholders informed throughout the incident response process.
- Communicate with legal teams, regulatory bodies, and, if necessary, the public.
POST-INCIDENT REVIEW
Lessons Learned
- Conduct a post-incident review meeting with all relevant parties to discuss what worked well and what can be improved.
- Document lessons learned and update the Incident Response Plan accordingly.
Continuous Improvement
- Implement recommendations from the post-incident review.
- Regularly review and update security policies, procedures, and training programs.
ONGOING SUPPORT
Managed Security Services
- Offer ongoing monitoring and incident response services to ensure continuous protection.
- Provide regular security assessments and updates.
Training and Readiness
- Maintain a dedicated support line for clients to report incidents or seek assistance.
- Offer periodic check-ins and proactive security advice.
